MALE ANATOMY

As you advance through the process of puberty, your body will develop and change shape in different ways. By understanding your own anatomy – more specifically, the male reproductive system – you can stay empowered around your health and rest assured that these changes are normal.

Anus: Opening where the gastrointestinal tract ends and exits the body.

Bladder: A hollow elastic organ that collects and stores urine from the kidneys before disposal by urination.

Corpus cavernosum: The mass of spongy tissue surrounding the male urethra within the penis that, when filled with blood, creates an erection.

Ejaculatory duct: A duct that passes through the prostate and transports semen during ejaculation.

Penis: External male sex organ. Urine and seminal semen pass through the penis.

Prostate: A walnut to golf ball-sized organ located below the bladder. The prostate secretes a fluid that protects sperm and sits just in front of the rectum.

Rectum: The lowest part of the digestive system, its function is to excrete feces from the human body.

Seminal Vesicle: One of two small organs beneath the bladder and connected to the urethra that plays a major role in producing seminal fluid (semen).

Testis: The primary male reproductive organs and pair of glands with two essential functions – producing sperm and secreting hormones, primarily testosterone.

Urethra: Tube from which you urinate. The urethra carries urine from the bladder to the urethral opening. In males, the urethra runs through the penis and carries pre-ejaculate and ejaculate.

Ureter: A tube that carries urine from the kidney to the urinary bladder.
